I 'naaeaem;

To all whom it may concern:

Be it known thatI, JoHN T. THOMPSON, a I

- citizen of the United States, residing at Wilmington', county of Newcastle, and State of Delaware, have invented a new anduseful form a part of thisspbcification.

My invention has for its object the construction ofa machine whereby powder strips of different sizes may be cut into pieces.

It also has for its object in such a machine to provide means wherebyinitially the speed of the machine may be adjusted for different speeds of delivery to it of the powder strips and also duringoperationmay beadjusted I the machine.

cone-pulley e on shaft f. On this shaft is the as that delivery speed varies. It is intended to act in conjunction with a machine' for forming such strips and to receive the strip directly therefrom and cut it into pieces.

I will firstdescribe the embodiment of my invention illustrated in the accompanying drawings and then point out the invention in the claims.

In the drawings, Figure 1 is a plan view of Fig. 2 is. a side elevation. Fig- 3 is an end view',;on a larger scale, with a portion of the frame broken away. Fig. 4 is a plan view of speed-gearing arrangement. Fig. 5 isa longitudinal sec ionalview on line 5 5, Fig. 4. Fig. 6 is a pla view of the feedrolls and carrying-frame. Fig. 7 is a side elevation of same. Fig. 8 is a transverse section on line 8 8, Fig. 6.. Fig. 9 is a'longitudinal section on line 9 9 Fig. 8. Fig. 10 is a transverse section on line 10 10, Fig. 7.

Application filed September 9, 1905- Serial No; 277,641 vi Patented cutter-disk g, mounted to revolvewith the shaft. On the end of shaft f is the bevel- ;mi 31., 1906. .',j

gear 79, meshing with the bevel-gear e on shaft 7, on which are the gears k of diflerent diameters.

n, carrying gear 0, which gear 0 is used "tocon Splined upon the shaft '1 is: the gear m, and pivoted upon shaft i is the arm nect the gear m'and one of the gears k. .1 'An arm" p, connected to arm'n, projects beyond the machine and has connected to it a pin or stop g, which is adapted to enter one ofthe orifices r in the plate 8. By swinging the arm n upward and arm" p downward the gears m and 0 may be moved-along the shaft Z, so as to bring the gears in position that the gear 0 will connect the gear m and the desired gear k to give the desired speed of rotation to shaft Z. fices 1' the gears. may beheld in-'the;desired position.

which is supported loosely upon the shaft 1 and rod u, arethe sets of rollers, each set comprising two upper rollers 1) w and two-lower rollers 11: y. The upper rollers 'v 'w revolve in bearings in the carriage or, housing The lower rollers 00 are mounted on a sleeve Mounted upon a carriage or housing t,

By means of the pin 'q and orisplined upon the shaft Z, and the lower rollers 'y are mounted on a sleeve loose upon the rod u. The pass or opening between diflerent'sets of rolls are different sizes. (See Figs. 10 and 11.) Connecting the end of the shaft land rod 11. is the cross-head 3 through which extends the rod,1,having at its outer end the handle 2 and having a threaded portion 3' working in a threaded portion 4 of the housing or carriage. By this construct on the carriage and rolls may be moved longitud nally. The outer roll of the rolls x-has a gear 7 connected to it by a pin 26, the outer roll of the rolls y a gear 8 connected to it bya pin, and the two gears are connected by a gear 9, sleeved on the rod 1. Between the rolls and the cutter-disk g is the disk 5, mounted so as to befrotatable and having the orifices 6 corres onding to. the .openings or passes in the m1 s. The position 'of this disk is such that an orifice at one face of the plate is contiguous to the mouth of the pass in the rolls, and the same orifice atv the opposite face of the disk is in line'with the cutters of the cutting-disk. By moving thecarr1age as described and rotating the disk 5 the desired size of pass between the rolls and the corresponding sized orifice in the disk 5 will be in alinement with each other and in proper plate 13. Projecting from and secured to' this plate are the threaded jaws 14 15, one

adapted to engage one thread of the rod 10,

the other the other thread. From the op 0- site side of the plate projects the belt-shifter 16, between which the belt (I rests. 17 is a handle at end of rock-shaft 12. By moving this handle the shaft 12 may be rocked and either jaw 14 or jaw 15 brought into engagement with the threaded shaft 10. I Then this is done, the belt-shifter moves longitudinally, carrying the belt over the cone-pulley, and thus either increasing or decreasing the speed of shaft and thus shaft Z. This the operator may o during the operation of the machine and without reference to the gears 'm and 7c.

In order to limit the travel of the jaws 14 and 15, I provide at each end of the rod 10 a cam-sto 18, which when the jaws reach it acts to isengage thejaws. I

19 is a chute adapted to receive the cut pieces of ground strips.

ranch way 20 normally closed by the gate 21. This gate is operated by the gear 22, which in turn is operated by the gear 23 on the shaft 24. At the end of this shaft is the crank 25, connected by the connectin -rod 26 with the crank 27, o eratedby hand e 28. By operating the-han e 28 the gate may be moved to close the main chute 19 and open the branch chute 20 to carry defective pieces away from the main receptacle.

In order that the operator may see the character of owder ieces that are being cut and delivere 'from t e machine, I provi e an inclined mirror 29 at the back of the machine, which is at such an angle that it reflects the powder pieces as they pass from the machine 1nto view of the o erator.

With my machine the rolls v, 'w, an, andy of the desired size pass from the strip and are brou ht into conjunction with the corre-v "spon in' orifice of the disk 5. The ear m is .broug t into connection with the esired ear 7c. The strip from the press is carried by the rolls to the cutters, where it is cut into pieces and falls into the chute. During the operation of the machine the speed is reguand improperly cut lated to conform to the delivery of the strip to the rolls by theth'readed rod 10 and its coacting parts, and the admixture of properly ieces in the same rece 'tacle 1s prevented y the operation of t e gate 21, as described. 7

My machine is adapted for varying sizes of driven or rotated by This chute has a strips, and also can readily be adjusted for difierent speeds of production of the strip, and can also. during '0 eration be adjusted to accommodate for c anges in the speed of delivery.

As stated, my machine is adapted to receive the strip direct from the machine and cut it up into lengths. In Fig. 16, 31 is the machine in which the strip is formed, and 32 the strip itself.
